Personal care compositions

ABSTRACT

A composition suitable for topical application, for example, is provided. In some examples, the composition can include particular cyclic oligosaccharides, a fragrance, and a volatile solvent. The compositions disclosed herein may provide a longer lasting fragrance.

TECHNICAL FIELD

The present disclosure generally relates to compositions comprising particular cyclic oligosaccharides, a fragrance, and a volatile solvent; and methods relating thereto.

BACKGROUND

Consumers often desire personal care compositions that deliver pleasant fragrances during and/or after application of the product. However, producing such products is often challenging for numerous reasons. For example, fragrances are often prematurely lost because many fragrances are relatively highly volatile and thus evaporate quickly after application. Because the amount of the fragrance that is released into the surrounding area generally decreases after application of a personal care composition, a consumer is likely to perceive potentially minimal or no fragrance odor character after time. Therefore, there is a need for improved personal care compositions that can deliver pleasant fragrances for extended periods of time during and after application of the product.

SUMMARY

DETAILED DESCRIPTION

While the specification concludes with the claims particularly pointing and distinctly claiming the invention, it is believed that the present invention will be better understood from the following description.

The devices, apparatuses, methods, components, and/or compositions of the present invention can include, consist essentially of, or consist of, the components of the present invention as well as other ingredients described herein.

All percentages and ratios used herein are by weight of the total composition and all measurements made are at 25° C., unless otherwise designated.

All measurements used herein are in metric units unless otherwise specified.

Reference within the specification to “embodiment(s)” or the like means that a particular material, feature, structure and/or characteristic described in connection with the embodiment is included in at least one embodiment, but it does not mean that all embodiments incorporate the material, feature, structure, and/or characteristic described. Furthermore, materials, features, structures and/or characteristics may be combined in any suitable manner across different embodiments and materials, features, structures and/or characteristics may be omitted or substituted from what is described.

“Free of” means that the stated ingredient has not been added to the composition. However, the stated ingredient may incidentally form as a byproduct or a reaction product of the other components of the personal care composition.

“Nonvolatile” refers to those materials that are liquid under ambient conditions and which have a measurable vapor pressure at 25° C. These materials typically have a vapor pressure less than about 0.01 mmHg, and an average boiling point typically greater than about 250° C.

“Soluble” means at least about 0.1 g of solute dissolves in 100 ml of solvent at 25° C. and 1 atm of pressure.

“Substantially free” of means an amount of a material that is less than 1%, 0.5%, 0.25%, 0.1%, 0.05%, 0.01%, or 0.001% by weight of a composition.

Cyclic oligosaccharides, and in particular cyclodextrins, have been used as a means to deliver a moisture-triggered fragrance from non-polar systems. In this regard, a fragrance is typically encapsulated within the cyclodextrin and is released when moisture is introduced into the system. One of the challenges of delivering a similar moisture-triggered fragrance release system in polar form is that the polar environment will typically release the fragrance within the system itself and not provide a long lasting fragrance.

Surprisingly, it has been found that limiting the amount of nonvolatile solvents in polar and aqueous compositions as described herein may dramatically improve the benefit of a long lasting fragrance provided by the cyclic oligosaccharides.

Cyclic Oligosaccharides

The compositions described herein may include a cyclic oligosaccharide. As used herein, the term “cyclic oligosaccharide” means a cyclic structure comprising six or more saccharide units. The cyclic oligosaccharides can have six, seven, or eight saccharide units or mixtures thereof. It is common in the art to refer to six, seven and eight membered cyclic oligosaccharides as α, β, and γ, respectively. The cyclic oligosaccharides that may be useful include those that are soluble in water, ethanol, or both water and ethanol. The cyclic oligosaccharides useful herein may have a solubility of at least about 0.1 g/100 ml, at 25° C. and 1 atm of pressure in either water, ethanol, or both water and ethanol. The compositions disclosed herein may comprise from about 0.001% to about 40%, from about 0.1% to about 25%, from about 0.3% to about 20%, from about 0.5% to about 10%, or from about 0.75% to about 5%, by weight of the composition, of a cyclic oligosaccharide. The compositions disclosed herein may comprise from 0.001% to 40%, from 0.1% to 25%, from 0.3% to 20%, from 0.5% to 10%, or from 0.75% to 5%, by weight of the composition, of a cyclic oligosaccharide.

The cyclic oligosaccharide may comprise any suitable saccharide or mixture of saccharides. Examples of suitable saccharides include, but are not limited to, glucose, fructose, mannose, galactose, maltose, and mixtures thereof. The cyclic oligosaccharide, or mixture of cyclic oligosaccharides, may be substituted by any suitable substituent or mixture of substituents. Herein the use of the term “mixture of substituents” means that two or more different suitable substituents may be substituted onto one cyclic oligosaccharide. Suitable examples of substituents include, but are not limited to, alkyl groups, hydroxyalkyl groups, dihydroxyalkyl groups, carboxyalkyl groups, aryl groups, maltosyl groups, allyl groups, benzyl groups, alkanoyl groups, and mixtures thereof. These substituents may be saturated or unsaturated, straight or branched chain. For example, the substituents may include saturated and straight chain alkyl groups, hydroxyalkyl groups, and mixtures thereof. The alkyl and hydroxyalkyl substituents, for example, may also be selected from C₁-C₈ alkyl or hydroxyalkyl groups, alkyl and hydroxyalkyl substituents from C₁-C₆ alkyl or hydroxyalkyl groups, and alkyl and hydroxyalkyl substituents from C₁-C₄ alkyl or hydroxyalkyl groups. The alkyl and hydroxyalkyl substituents may be, for example, propyl, ethyl, methyl, and hydroxypropyl.

In addition to the substituents themselves, the cyclic oligosaccharides may have an average degree of substitution of at least 1.6, wherein the term “degree of substitution” means the average number of substituents per saccharide unit. For example, the cyclic oligosaccharides may have an average degree of substitution of less than about 2.8 or from about 1.7 to about 2.0. The average number of substituents may be determined using common Nuclear Magnetic Resonance techniques known in the art. Examples of cyclic oligosaccharides useful herein include methyl-α-cyclodextrins, methyl-β-cyclodextrins, hydroxypropyl-α-cyclodextrins, hydroxypropyl-β-cyclodextrins, and mixtures thereof.

Volatile Solvents

The compositions described herein may include a volatile solvent or a mixture of volatile solvents. The volatile solvents may comprise greater than 10%, greater than 30%, greater than 40%, greater than 50%, greater than 60%, greater than 70%, greater than 80%, greater than 90% or greater than 95%, by weight of the composition. The volatile solvents useful herein may be relatively odorless and safe for use on human skin. Suitable volatile solvents may include C₁-C₄ alcohols and mixtures thereof. For example, ethanol may be used as the volatile solvent. Some other non-limiting examples of volatile solvents include methanol, propanol, isopropanol, butanol, and mixtures thereof.

Nonvolatile Solvents

The composition may comprise a nonvolatile solvent or a mixture of nonvolatile solvents. Non-limiting examples of nonvolatile solvents include benzyl benzoate, diethyl phthalate, isopropyl myristate, propylene glycol, dipropylene glycol, triethyl citrate, and mixtures thereof. If present, the nonvolatile solvent may be included at a weight ratio of the nonvolatile solvent to the cyclic oligosaccharide of less than 1:1, less than 1:2, less than 1:10, or less than 1:100. The nonvolatile solvent may also be included at a weight ratio of the nonvolatile solvent to the cyclic oligosaccharide of less than about 1:1, less than about 1:2, less than about 1:10, or less than about 1:100 From a weight percentage perspective, the nonvolatile solvent may be included at a level of from about 0.5% to about 5% or from about 1% to about 3% by weight of the composition. Some suitable nonvolatile solvents may provide skin or other benefits since they are left behind on the skin upon applying the composition to one's skin. For example, panthenol, panthenyl triacetate, or other Vitamin B5 derivatives can act as both a nonvolatile solvent and a skin conditioning agent.

Fragrances

The composition may comprise a fragrance. As used herein, “fragrance” is used to indicate any odoriferous material. Any fragrance that is cosmetically acceptable may be used in the composition. For example, the fragrance may be one that is a liquid at room temperature. Generally, the fragrance(s) may be present at a level from about 0.01% to about 40%, from about 0.1% to about 25%, from about 0.25% to about 20%, or from about 0.5% to about 15%, by weight of the composition.

A wide variety of chemicals are known as fragrances, including aldehydes, ketones, and esters. More commonly, naturally occurring plant and animal oils and exudates comprising complex mixtures of various chemical components are known for use as fragrances. Non-limiting examples of the fragrances useful herein include pro-fragrances such as acetal pro-fragrances, ketal pro-fragrances, ester pro-fragrances, hydrolyzable inorganic-organic pro-fragrances, and mixtures thereof. The fragrances may be released from the pro-fragrances in a number of ways. For example, the fragrance may be released as a result of simple hydrolysis, or by a shift in an equilibrium reaction, or by a pH-change, or by enzymatic release. The fragrances herein may be relatively simple in their chemical make-up, comprising a single chemical, or may comprise highly sophisticated complex mixtures of natural and synthetic chemical components, all chosen to provide any desired odor.

The fragrances may have a boiling point (BP) of about 500° C. or lower, about 400° C. or lower, or about 350° C. or lower. The BP of many fragrances are disclosed in Perfume and Flavor Chemicals (Aroma Chemicals), Steffen Arctander (1969). The C log P value of the fragrances may be about 0.1 or greater, about 0.5 or greater, about 1.0 or greater, and about 1.2 or greater. As used herein, “C log P” means the logarithm to the base 10 of the octanol/water partition coefficient. The C log P can be readily calculated from a program called “C LOG P” which is available from Daylight Chemical Information Systems Inc., Irvine Calif., USA. Octanol/water partition coefficients are described in more detail in U.S. Pat. No. 5,578,563.

It should be appreciated that compositions of the present invention may also be devoid of a propellant.

Other Ingredients

The compositions disclosed herein also contain a variety of other ingredients that may render the composition more cosmetically or aesthetically acceptable or provide the composition with additional usage benefits. These other ingredients are well-known to those skilled in the art. These include any cosmetically acceptable ingredient such as may be found in the CTFA International Cosmetic ingredient Dictionary and Handbook, 7 th edition, edited by Wenninger and McEwen, (The Cosmetic, Toiletry, and Fragrance Association, Inc., Washington, D.C., 1997). As used herein “cosmetically acceptable” means a material (e.g., compound or composition) that is suitable for use in contact with skin, hair, or other suitable substrate. For example, the compositions may include alcohol denaturants such as denatonium benzoate; UV stabilizers such as benzophenone-2; antioxidants such as tocopheryl acetate; preservatives such as phenoxyethanol, benzyl alcohol, methyl paraben, propyl paraben; dyes; pH adjusting agents such as lactic acid, citric acid, sodium citrate, succinic acid, phosphoric acid, sodium hydroxide, sodium carbonate; deodorants and antimicrobials such as farnesol and zinc phenolsulphonate; humectants such as glycerine; oils; skin conditioning agents such as allantoin, panthenol and other Vitamin B5 derivatives; cooling agents such as trimethyl isopropyl butanamide and menthol; hair conditioning ingredients such as panthenol, panthetine, pantotheine, panthenyl ethyl ether, and combinations thereof; silicones; salts in general, such as potassium acetate and sodium chloride; and mixtures thereof. When present, these additional ingredients may be present at a level of less than 10%, by weight, of the total composition. Embodiments of the present invention include feminine and adult incontinence sprays/spritzes. Intimate skin that was shaven or irritated due to mechanical or chemical contact (e.g., prolonged exposure to menses and urine) can be sensitive to the volatile solvents included in the compositions of the present invention. Thus, skin conditioning agents such as, for example, Vitamin B5 (e.g., panthenol, panthenyl triacetate, and mixtures thereof) derivatives, are useful in the composition to help mitigate stinging or general discomfort from the volatile solvent.

Antiperspirant Active

The compositions described herein may be free of, substantially free of, or may include an antiperspirant active (i.e. any substance, mixture, or other material having antiperspirant activity). Examples of antiperspirant actives include astringent metallic salts, like the inorganic and organic salts of aluminum, zirconium and zinc, as well as mixtures thereof. Such antiperspirant actives include, for example, the aluminum and zirconium salts, such as aluminum halides, aluminum hydroxyhalides, zirconyl oxyhalides, zirconyl hydroxyhalides, and mixtures thereof.

Article of Manufacture

The composition may be included in an article of manufacture comprising a spray dispenser. The spray dispenser may comprise a vessel for containing the composition to be dispensed. The spray dispenser may comprise an aerosolized composition (i.e. a composition comprising a propellant) within the vessel as well. Other non-limiting examples of spray dispensers include non-aerosol dispensers (e.g. vapor sprays), manually activated dispensers, pump-spray dispensers, or any other suitable spray dispenser available in the art.

Method of Use

The compositions described herein may be packaged with any container known in the art or with any spray dispenser suitable for delivering the composition to a substrate. The composition may be applied to any substance where moisture is available to trigger the release of the fragrance. When the composition is applied to the human body, the composition may be applied to any area of the skin or may be applied to any area of the body. Alternatively, the composition may be applied to any article, such as a fabric, or any absorbent article including, but not limited to, feminine hygiene articles, diapers, and adult incontinence articles. For example, the composition may be used as a body spray, feminine spray, adult incontinence spray, baby spray, or other spray. A consumer may apply a feminine spray or adult incontinence spray to their body as well as one or more exterior surfaces of a feminine hygiene/incontinence article. A benefit of allowing a consumer to self-dose the composition onto a pre-purchased article is that the consumer can choose how much composition is desired for each article use and vary the application volume as needed. Some feminine hygiene and adult incontinence articles may contain a fragrance and/or odor managing material (e.g., zeolites, absorbent gelling materials) within the article. And some feminine hygiene and adult incontinence articles are devoid of such materials. Consumers accordingly can apply compositions of the present invention to outer surfaces of articles with or without a fragrance/odor managing material within the article.

Feminine/Adult Incontinence Applications

While the specification has illustrated suitable fragrance materials above, the disclosure below highlights some exemplary (non-limiting) fragrance compounds that can be particularly suitable for compositions of the present invention when they are in the form of a feminine hygiene or adult incontinence product. In some embodiments, fragrance compounds having a “thiol vapor pressure suppression index” (TVPS) of more than 20 may be suitable. Thiol Vapor Pressure Suppression (TVPS) index is a measure of the reduction in butanethiol concentration in the headspace by a compound, as measured using a fast GC instrument, the zNose 7100 (Electronic Sensor Technologies, Newbury Park, Calif.). Before any measurements the instrument is calibrated according to manufacturer's instructions under the same experimental settings. The instrument has a DB-5 column (EST Part No. SYS7100C5, Electronic Sensor Technologies, Newbury Park, Calif.) 1 m in length, 0.25 μm phase thickness, and 0.25 mm in diameter. The experimental settings for TVPS measurements are:

Sampling time: 10 s

Sensor Temperature: 40° C.

Initial Column Temperature: 40° C.

Inlet Temperature: 40° C.

Valve Temperature: 40° C.

Column Temperature Ramp Rate: 10 C.°/s

Final Column Temperature: 200° C.

TVPS of a compound is measured in the following way: 100 μl±1 μl of a 1% v/v butanethiol (99%, purity) solution in ethanol (200 proof) is added into a 1 ml vial (8×40 mm). These vials are borosilicate glass straight walled vial. A suitable butanethiol is item 112925 from Sigma-Aldrich (Sigma-Aldrich, St. Louis, Mo.). In another 1 ml vial (8×40 mm), 5 μl±0.2 μl of the compound is added. Both open vials are then placed inside a 20 ml headspace vial (22×75 mm), and the vial is immediately sealed using a screw thread closure with PTFE/Silicone septa. The vial is heated to 37° C. for 4 hours. After 4 hours, the vial is removed from the oven and let to equilibrate at 25° C.±2° C. for 15 minutes. The headspace inside the vial is sampled using the zNose following the experimental protocol outlined above. Samples with butanethiol alone, and the volatile active alone, are run using the same protocol to identify the peaks for both materials. An acceptable retention index for butanethiol is 720±30. If the peaks butanethiol peak and the volatile material peak co-elute, one skilled in the art can modify the protocol settings to separate those peaks. A minimum resolution of 1.5 should be obtained. For example one can change the column temperature ramp rate. In between samples, the instrument needs to be cleaned to remove any trace materials. To clean the instrument, the instrument is run without samples as needed until no peaks greater than 100 counts are observed.

The amount of butanethiol in the headspace is measured from the area of the peak on the chromatograph for butanethiol (A_(BtSH,Rx)). To calculate the percentage of butanethiol reduction in the headspace, a control with the butanethiol solution without the volatile material is run in the same manner and the area is measured as well (A_(BtSH,C)). TVPS is then measured as the percentage reduction in butanethiol area calculated using the following formula:

${TVPS} = {\frac{A_{{BtSH},C} - A_{{BtSH},{Rx}}}{A_{{{BtSH},C}\;}} \times 100}$

Fragrance compounds having a TVPS higher than 20 include, but are not limited to, (a) melonal, adoxal, trans-2-hexenal, ligustral, Floral Super, Florhydral, 5-methyl-2-thiophene-carboxaldehyde, hydratropic aldehyde, undecenal, 9-undecenal, 10-undecenal, trans-4-decenal, cis-6-nonenal, isocyclocitral, precyclemone b, (E)-2,(z)-6-nonadienal, undecyl aldehyde, methyl-octyl-acetaldehyde, Lauric aldehyde, silvial, vanillin, and floralozone.

All these compounds in list (a) above are particularly reactive toward malodourant molecules containing Sulphur atoms (thiol type malodors, typically associated with protein degradation e.g. in menstrual fluids, feces, food etc). The primary function of the reactive compounds is to chemically react with malodors, such as malodourant molecules containing Nitrogen atoms (amine type odors, typically deriving from the degradation of urine or certain foods like onions) and/or malodourant molecules containing Sulphur atoms (thiol type malodors, typically associated with protein degradation e.g. in menstrual fluids, feces, food etc). Ammonia/amines are one component of malodor associated with the absorption of bodily fluids, such as menses or urine. For example, ammonia/amines are typically present in high amounts in absorbent products used for urine absorption due to degradation of urea. Ammonia/amines and their derivatives can react with aldehydes and/or ketones to form imines (according to the so-called Schiff base reaction).

This reaction is catalyzed by enzymes and/or by a slightly acidic pH 4 to 5. The moderate acid requirement is necessary to allow protonation of the hydroxyl intermediate to allow water to leave.

Malodourant sulphur based compounds are typically generated by the degradation of proteins e.g. in menstrual fluids feces or food and so their control is particularly important in menstrual absorbent articles such as sanitary napkins or pantyliners as well as in other absorbent articles which get in contact with other proteinaceous materials such food residues or feces. The mechanism of action is not fully understood at the moment, but it is believed that it is connected to the fact that Thiols can react with aldehydes and ketones to form thioacetals and thioketals.

In principle the chemical reactions described above can be obtained from any aldehyde, but in practice the reactivity of aldehydes in these type of reactions and in the specific context of an absorbent article is very different. The reactive compounds of the present invention are effective in reacting with Nitrogen based malodourant molecules and particularly effective in reacting with sulphur based malodourant molecules.

Preferred additional fragrance compounds are listed here below in lists (b), (c), (d) and (e). Suitable selected additional aldehydes and/or ketones include the following listed in list (b): hexyl cinnamic aldehyde, alpha-amylcinnamic aldehyde, p-anisaldehyde, benzaldehyde, cinnamic aldehyde, cuminic aldehyde, decanal, cyclamen aldehyde, p-t-butyl-alpha-methyldihydrocinnamaldehyde, 4-hydroxy-3-methoxycinnamaldehyde, vanillin isobutyrate, 2-phenyl-3-(2-furyl)prop-2-enal, ethyl vanillin acetate, vanillin acetate, heptanal, lauryl aldehyde, nonanal, octanal, phenylacetaldehyde, phenyl propyl aldehyde, salycil aldehyde, citral, 2,4-dihydroxy-3-methylbenzaldehyde, 2-hydroxy-4-methylbenzaldehyde, 5-methyl salicylic aldehydes, 4-nitrobenzaldehyde, o-nitrobenzaldehyde, 5-ethyl-2-thiophenecarbaldehyde, 2-thiophenecarbaldehyde, asaronaldehyde, 5-(hydroxymethyl)-2-furaldehyde, 2-benzofurancarboxaldehyde, 2,3,4-trimethoxybenzaldehyde, protocatechualdehyde, heliotropine, 4-ethoxy-3-methoxy benzaldehyde, 3,4,5-trimethoxybenzaldehyde, 3-hydroxybenzaldehyde, o-methoxycinnamaldehyde, 3,5-dimethoxy-4-hydroxycinnamaldehyde, 2,8-dithianon-4-3n-4-carboxaldehyde, sorbinaldehyde, 2,4-heptadienal, 2,4-decadienal, 2,4-nonadienal, 2,4-nonadienal, (E,E)-,2,4-octadien-1-al, 2,4-octadienal, 2,4-dodecadienal, 2,4-undecadienal, 2,4-tridecadien-1-al, 2-trans-4-cis-7-cis-tridecatrienal, piperonylidene propionaldehyde, 2-methyl-3-(2-furyl)acrolein, 2,4-pentadienal, 2-furfurylidene butyraldehyde, helional, lyral, 3-hexenal, safranal, veratraldehyde, 3-(2-furyl)acrolein, pyruvaldehyde, ethanedial, 1-(2,6,6-trimethyl-1-cyclohexenyl)pent-1-en-3-one; 4-(2,6,6-trimethyl-1-cyclohexen-1-yl)-3-Buten-2-one; 4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-one, 5-(2,6,6-Trimethyl-2-cyclohexen-1-yl)4-penten-3-one, (E)-4-(2,2-dimethyl-6-methylidenecyclohexyl)but-3-en-2-one.

These are volatile materials which are well complexed in particular when the complexing agent is a cyclodextrin and are release very quickly upon contact with a water based liquid. Their presence allows the absorbent article to respond more quickly to an insult of malodourant liquid by releasing a compound that have a good general masking effect against malodors, in particular, being very volatile, reduces the vapor pressure of other malodourant compounds slowing down their evaporation rate.

Prepare a 3 inch by 5 inch cardboard, professional aerosol testing blotter card (available from Orlandi Inc.) for each sample to be tested. Pre-weigh each blotter card with an analytical balance. Spray each sample evenly onto a blotter card. This can be done using a 3 ounce plastic bottle (Matrix Packaging) fitted with a 3 ounce spray actuator from Seaquist Perfect Dispensing. The blotter card should be weighed after the sample is sprayed to ensure that approximately 0.050 grams±0.0025 of sample was sprayed onto the blotter card. If the blotter card was not evenly wet among the application area upon visual evaluation or if the amount of sample sprayed was not approximately 0.050 grams±0.0025, the blotter card should be disposed and the process should be repeated.

Once all samples are prepared, the blotter card should be placed with the application side face up on a paper towel. The blotter card should be allowed to dry at room temperature for about 4 hours. After drying, using a similar plastic bottle fitted with the spray actuator as described above, spray each sample once with distilled water directly over the application area of the blotter card. Immediately after spraying, place each blotter card containing a sample into a different 7 ounce clear polyethylene terephthalate cup containing a lid. This can be done by rolling the blotter card into a cylinder across the long axis of the blotter card and arranging the blotter card so that the application side is facing the center of the cup. Once placed, the lid to the polyethylene terephthalate cup should be closed and the samples are ready for analysis.

Next, prepare a zNose Fast-GC Analyzer (Model #MEA007100) with DB-624 column from Electronic Sensor Technology, Inc., (hereinafter referred to as “zNose”) or equivalent for analysis. Prior to running the samples, the zNose should be cleaned and calibrated. To clean and calibrate the zNose, first turn on the zNose, open the helium valve, and open the program, MicroSense 4.5. Allow all parts of the instrument to reach their appropriate temperatures which can take approximately 15 minutes.

If the helium in the zNose is low, connect a helium tank to the back of the zNose (marked “Helium”) by way of a hose, open the valve on the helium tank, and fill until the zNose pressure gauge reaches about 1000 psi. Once full, close the valve on the helium tank, release the pressure from the hose, and remove the hose from the zNose.

To clean the inlet and needle of the zNose, fill half of a vial with methanol and insert the bubbler so that the tip of the bubbler is fully emerged in the methanol. Place the vial on a sampler needle. In the control panel, type in 90 seconds and select “Pump” to bubble the methanol. Next, hit the “Fire Trap” twice in the control panel. Raise the column temperature to 190° C. in the test settings for 15 seconds. Once complete, reduce the column temperature back to 40° C. Back the sensor once by clicking the proper button on the monitoring tools. Run a high temperature blank, raising the sensor temperature to 100° C. and save this file. The blank should be an empty headspace of the same container in which the sampling is done. Run a low temperature blank by lowering the sensor temperature to 40° C. If large peaks remain, repeat the cleaning procedures as stated above. If large peaks remain after cleaning, refer to the Maintenance and Repair section in the zNose's accompanying manual. If peaks are less than 300 counts and are in higher KI, the contamination peaks may be tagged and accounted for in the calculations.

The zNose is clean and operational when all peaks are below 100 counts as per manufacturer's instructions. Ensure the ‘Test settings’ are set according to the following: Sensor (50 C), Column (40 C), Valve (145 C), Inlet (200 C), Trap (200 C), Pump Time (10 seconds). Once test settings are set, calibrate the zNose with a n-alkanes standard as stated in the zNose's accompanying manual. This will ensure the zNose is operating according to the manufacturer's standards.

Once the zNose is clean and calibrated, create a new alarm file. The new alarm file should contain no tagged peaks. Samples should be analyzed randomly. Analyze the 1^(st) sample according to the manufacturer's instructions. A cleaning step should be performed after each sample is analyzed by bubbling methanol for 5 seconds. Next, a blank should be analyzed to ensure that no peaks remain. If no peaks remain, analyze the 1^(st) sample a second time. Perform a cleaning step with bubbling methanol for 5 seconds followed by an analysis of a blank to ensure that no peaks remain. If no peaks remain, analyze the 1^(st) sample a third time. Perform a cleaning step with bubbling methanol for 5 seconds followed by an analysis of a blank to ensure that no peaks remain. Repeat the above steps for each sample. All testing should take place within an hour from the analysis of the first sample and within 4 to 5 hours after the application of the sample to the blotter card.

Once all samples have been analyzed, transfer the data to Microsoft® Excel® or equivalent and sum the total area under all the peaks associated with each sample. For each sample, there should be a ‘total peak area’ representing each of the 3 runs per sample. Calculate the average, standard deviation, and the percent relative standard deviation (i.e., % RSD) for each sample. A mean, standard deviation, and % RSD should now be available for each sample based on a sample size of n=3.

Fragrance Expert Panel

Evaluations were conducted under controlled environmental conditions by a trained panel using the following standardized procedures. Approximately 10-20 expert panelists participated in each evaluation. Compositions were sprayed using a 3 ounce plastic bottle (Matrix Packaging) fitted with a 3 ounce spray actuator from Seaquist Perfect Dispensing. Compositions were shaken and then sprayed for 2 seconds onto the forearm of a panelist, approximately 2 to 6 inches below the wrist in an area preferably with minimal hair. The actuator was held about 6 inches away from the forearm. The process was repeated with the other forearm. Each panelist rated the intensity of the fragrance, from 1-8, in order of increasing intensity (e.g. a rating of 1 being the lowest intensity and a rating of 8 being the highest intensity) before application of the composition (baseline), and at 15 min, 30 min, and 60 min after spraying of the composition. At times 45 min, 90 min, and 180 min after spraying of the composition, the forearms were sprayed with one spritz of water using a 3 ounce plastic bottle (Matrix Packaging) fitted with a 3 ounce spray actuator from Seaquist Perfect Dispensing and the panelist rated the intensity before and after the water spritz. The ratings were recorded and subsequently analyzed by the Wilcoxon method.

Fragrance Untrained Panel

Evaluations were conducted under controlled environmental conditions by an untrained panel using the following standardized procedures. Approximately 5 untrained panelists participated in each evaluation. Compositions were sprayed onto a 3 inch by 5 inch cardboard, professional aerosol testing blotter card (available from Orlandi Inc.) using a 3 ounce plastic bottle (Matrix Packaging) fitted with a 3 ounce spray actuator from Seaquist Perfect Dispensing. An amount of 0.050 g±0.0025 of composition was applied to each blotter card. The amount sprayed onto each blotter card can be confirmed using an analytical balance. Following the spraying of the composition, the blotter cards were allowed to dry for 24 hours. After drying, blotter cards were sprayed with approximately 0.025 g of water using a 3 ounce plastic bottle (Matrix Packaging) fitted with a 3 ounce spray actuator from Seaquist Perfect Dispensing and placed into a 7 ounce clear polyethylene terephthalate cup for evaluation. Panelists were instructed to rate the intensity of the fragrances from 1-7 in order of increasing intensity (e.g. a rating of 1 being the lowest intensity and a rating of 7 being the highest intensity). The ratings were recorded and subsequently analyzed by the Wilcoxon method.

Examples

The following examples are given solely for the purpose of illustration and are not to be construed as limiting the invention, as many variations thereof are possible.

Table 1 below illustrates the effect of nonvolatile solvents on the release of a fragrance into the headspace. The total area count for the compositions shown in Table 1 were measured using the Headspace Test Method disclosed herein. Examples contained 0.25% by weight of the composition of a typical fragrance, 1% by weight of the composition of methylated-β-cyclodextrin (shown as “mβCD” in Table 1), and the nonvolatile solvents, dipropylene glycol or triethyl citrate at the indicated percentiles. The remainder of the formulation was balanced to 100% with ethanol. Formulations were mixed to ensure homogeneity.

Comparing Example B and Example C to Example A from Table 1, the addition of either dipropylene glycol or triethyl citrate decreased the amount of fragrance released into the headspace by approximately 21% and 33%, respectively. Increasing the concentration of either dipropylene glycol or triethyl citrate relative to methylated-β-cyclodextrin in the composition further decreased the amount of fragrance released into the headspace in a dose-dependent manner. For example, comparing Example D to Example B, increasing the concentration of dipropylene glycol relative to methylated-β-cyclodextrin decreased the amount of fragrance released into the headspace from a count of 159514 for Example B to a count of 70821 for Example C. Comparing Example H to Example A from Table 1, the inclusion of dipropylene glycol in the composition at a ratio of 1:1 of dipropylene glycol:methylated-β-cyclodextrin reduced the amount of fragrance released into the headspace by approximately 95%. Similar trends were observed when triethyl citrate was included in the composition in place of dipropylene glycol. These data suggest that the inclusion of nonvolatile solvents can suppress the release of a fragrance from a composition including methylated-β-cyclodextrin. The data further suggests that the ratio of nonvolatile solvent to methylated-β-cyclodextrin is an important consideration for formulating such compositions in view of maximizing the release of the fragrance into the headspace.

Table 2 below illustrates the influence of nonvolatile solvents on the release of a fragrance into the headspace as determined by the Fragrance Untrained Panel described herein. Example 1 included a ratio of nonvolatile solvent to methylated-β-cyclodextrin due to trace amounts of dipropylene glycol within the fragrance itself. Example 1, which contained the least amount of nonvolatile solvent relative to methylated-β-cyclodextrin, obtained the highest average ranking by the Fragrance Untrained Panel with a score of 7.0. Comparing Example 2 to Example 1, increasing the concentration of the nonvolatile solvent, dipropylene glycol, relative to methylated-β-cyclodextrin to a ratio of 1:4 resulted in average ranking of 6.0, a ranking statistically significantly lower than that attributed to Example 1. Comparing Example 3 to Example 1, increasing the concentration of the nonvolatile solvent, triethyl citrate, relative to methylated-β-cyclodextrin to a ratio of 1:5 resulted in an average ranking of 3.8, a statistically significantly lower ranking than attributed to Example 1.

Comparing Example 4 and Example 6 to Example 2, further increasing the concentration of the nonvolatile solvent, dipropylene glycol, relative to methylated-β-cyclodextrin to a ratio of 1:1 (Example 4) or 2:1 (Example 6) resulted in an average ranking of 3.6 and 2.6, respectively; a ranking statistically significantly lower than that attributed to Example 2. No significant difference was observed between Example 4 and Example 3, Example 5 and Example 3, Example 6 and Example 3, or Example 7 and Example 3. These data corroborate the findings obtained from the Headspace Test Method that the inclusion of nonvolatile solvents in such compositions can suppress the release of a fragrance and that the ratio of nonvolatile solvent to methylated-β-cyclodextrin is an important consideration for formulating such compositions in view of maximizing the release of the fragrance into the headspace.

Table 3 below illustrates the effect of nonvolatile solvents on the release of a fragrance into the headspace in aerosolized compositions as determined by the Fragrance Expert Panel described herein. Table 3 illustrates the average ratings of Panelists who rated the forearms of subjects 180 min after the spraying of Example 8, 9, and 10, before and after a spritz of water. Example 8 included the nonvolatile solvents, dipropylene glycol and isopropyl myristate, but did not include methylated-β-cyclodextrin. Example 9 included methylated-β-cyclodextrin and the nonvolatile solvents, dipropylene glycol and isopropyl myristate. Example 10 included methylated-β-cyclodextrin but did not include the nonvolatile solvents, dipropylene glycol and isopropyl myristate.

Comparing Example 8 to Example 9, the addition of methylated-β-cyclodextrin to the composition of Example 9 did not result in a statistically significant increase in the average ranking despite the increase in average scores when ratings were conducted before the application of the water. In contrast, after the application of water, Example 9 had a statistically significant increase in rating as compared to Example 8 (4.5 versus 4). Comparing Example 9 to 10, the exclusion of nonvolatile solvents as in Example 10 did not result in a statistically significant increase in the ranking by the Panelists as compared to Example 9 when ratings were conducted before the application of the water. Surprisingly, the exclusion of nonvolatile solvents as in Example 10 resulted in a statistically significant increase in the average ranking as compared to Example 9 when ratings were conducted after the application of water (4.9 versus 4.5). These data corroborate the findings obtained from the Headspace Test Method and the Fragrance Untrained Panel that the inclusion of nonvolatile solvents in such compositions can suppress the release of a fragrance.
